Seems that you got all the answers. Suppose a race organiser opt for including the R7,50 and the R9,90 (4,5% of R220,00) in the entree price of the long route. The new advertised entree fee is now R237,40 What about the championchip he also ordered (and got noting to do with the organisers) for R100,00, is championchip willing to pay for the credit card surcharge on the chip? The same applies to a charity donation as part of the entering procedure. As it stands now with the Carousel entrees, the participant pays 4,5% on these items as well. Who pays the 4,5% in the above example?
